It is well known that the composite laminates are suspicious to the various impact
events. Therefore, it is crucial to monitor the external impact forces. In some
previous studies for the impact force identification problem, the method using a
transfer function has been proposed. For the cases with given force locations in
advance, for example, Inoue et al. [1, 2] have experimentally obtained the transfer
function between impact forces and strain responses, and determined the impact
forces through the deconvolution method. Using the same relationship obtained
numerically, Doyle [3] proposed the similar technique for identifying an impact
force history in a time domain from the strain response.
